@Rage and Midna!

Install the "nightly tester tools" add-on (https://addons.mozilla.org/de/firefox/addon/6543). It allows to override the compatibilty check for add-ons. With the help of "nightly tester tools" unplug also works in firefox 3.5

HTH

This review is for a previous version of the add-on (2.003).
